Server communication: passing environment variables

This recipe shows how to pass environment variables to your tests

• See package.json file which runs Cypress with environment variables set. The variables that start with CYPRESS_ are extracted automatically. Other variables are copied from process.env in the setupNodeEvents function
• Additional variables can be passed via env object in cypress.config.js
• Extract any other variable from process.env using the setupNodeEvents function.
• Uses dotenv package to read the .env file in the Cypress configuraton
• Keep secret or private variables server-side and read them in your spec with cy.env(): cy.env(['secret', 'password']). Values stay on the server; only the keys you request are returned to the spec.
• Use Cypress.expose() (and the expose config / { expose: {...} } test/suite override) only for values that are safe to expose everywhere — they are serialized into the config and readable in the browser and across every origin.
